A few years ago I purchased some stainless steel trims for VW bug [last of the beetles] they are much the same profile as the strip from tail lights to bumper on FC 2 tone . I use stainless steel self tapping screws [6 gauge ] to attach as the strip will grip the head of the screw. The interesting thing is these strips are available aftermarket in aluminium and for the early Beetles in a wider strip . I have used this in many situations ,in hotrod interiors , exteriors , fastening hood linings , wrinkles in custom motorcycle seats , edging on under dash trays and much more .
